<P>PROBLEM TO BE SOLVED: To inspect cargoes by performing communication with all RFID tags affixed to the cargoes when conveying the cargoes by a forklift. <P>SOLUTION: A forklift 7 monitors the advancing degree of reading from the traveling position of the forklift 7 after advancing in a communication area of a reader and the number of RFID tags completing the reading, and when the advancing degree of reading is low, a command for changing the position of cargoes loaded on the forklift 7 is transmitted to the forklift 7. The forklift 7 moves a fork 20 in the vertical direction and the right and left direction according to the transmitted command so that the communication with the reader is possible by allowing the RFID tags to be escaped from a place of weak radio wave intensity. <P>COPYRIGHT: (C)2009,JPO&INPIT |
